Abstract

A seismic sensor that suppresses power consumption operates in a power-saving mode and a measurement mode in which the power consumption is larger than that in the power-saving mode. The seismic sensor includes a measurement unit that measures an acceleration, a filtering unit that, if the acceleration measured by the measurement unit exceeds a predetermined threshold, causes a shift from the power-saving mode to the measurement mode to be performed, and performs filtering on the measured acceleration, an earthquake determination unit that determines whether or not an earthquake has occurred based on the filtered acceleration, and an index calculation unit that, if where the earthquake determination unit determined that an earthquake has occurred, calculates an index value indicating the scale of the earthquake. A shift from the measurement mode to the power-saving mode is performed if the earthquake determination unit determined that no earthquake has occurred.

Collector plates 16a, 16b are arranged on the surfaces of the fuel cell stack 12 so that first main surfaces of the collector plates face the via conductor. Fixing plates 14a, 14b fix the collector plates 16a, 16b, with first main surfaces of the fixing plates facing second main surfaces of the collector plates 16a, 16b. Spacers 18a, 18b are arranged between the fuel cell stack 12 and the fixing plates 14a, 14b so as to adjust the distances from the surfaces of the fuel cell stack 12 to the first main surfaces of the fixing plates 14a, 14b to be equal to the thicknesses of the collector plates 16a, 16b. An adhesive 28 is softened by heating, thereby affixing the fixing plates 14a, 14b to the fuel cell stack 12 with the spacers 18a, 18b being interposed therebetween.

Abstract

Disclosed is a sensor cell for protecting a fuel cell in which hydrogen is used as a fuel. With the sensor cell, all of various impurities which are contained in the fuel hydrogen and in an oxidant gas and cause a deterioration in performance of the fuel cell are monitored by means of one sensor to protect the fuel cell. The sensor cell, which is for use in a system for protecting a fuel cell, comprises an impurity monitoring sensor that has been disposed on the upstream side of the fuel cell and is constituted of a hydrogen pump cell which is more sensitive to impurities contained in the fuel hydrogen than the fuel cell. The sensor cell is characterized in that an impurity is detected on the basis of a change in the hydrogen electrolysis reaction occurring at the anode and in the hydrogen generation reaction occurring at the cathode.

Abstract

A novel hydrogen separation membrane comprising an Nb-W-Mo alloy is obtained. Conditions for a method of hydrogen separation with this hydrogen separation membrane and for the hydrogen separation are selected in the following specific manner. The pressure of hydrogen (P) in each of hydrogen atmospheres in contact with the Nb-W-Mo alloy membrane and the amount of solid-solution hydrogen (C) present in the Nb-W-Mo alloy membrane are determined at temperatures (T). Based on the resultant data on temperatures (T), hydrogen pressures (P), and solid-solution hydrogen amounts (C), a PCT curve showing relationships among these three factors is drawn. A relationship between the amount of solid-solution hydrogen (C) and the brittle fracture of the Nb-W-Mo alloy membrane is determined from the PCT curve to evaluate a limiting solid-solution hydrogen amount, which relates to resistance to hydrogen embrittlement. A use temperature and primary-side and secondary-side hydrogen pressures are set on the basis of the evaluation.

Provided are a carbon dioxide sequestration device and method whereby carbon dioxide can be directly injected into a saline aquifer and efficiently sequestered in said saline aquifer. The end of an injection well (9) is provided with, for example, a whetstone filter (13). Carbon dioxide stored in a carbon dioxide tank (3) is pumped by a pump device (5). The pump device (5) sends the carbon dioxide in the carbon dioxide tank (3) to the injection well (9) via a pump while the carbon dioxide in the pump device is kept within a prescribed pressure range and a prescribed temperature range by a pressure-regulating valve, a temperature regulator, and the like. The carbon dioxide is sent into the injection well (9) in the direction of the arrow (A), passes through the filter (13) provided at the end of the injection well (9), and is injected into a saline aquifer (11). The carbon dioxide injected into the saline aquifer (11) forms microbubbles.

Abstract

A pipe joint comprising: a pressing nut into which a flexible pipe is inserted; a joint body into which the pressing nut is partially inserted; an elastic means which is released from locking engagement when pressed by the tip of the flexible pipe; a seal member; a retainer which engages with the flexible pipe; and an engagement mechanism for holding the pressing nut at a predetermined position relative to the joint body. The engagement mechanism comprises: a stop ring; an annular groove formed in the outer surface of the pressing nut so as to contain and support the stop ring; and engaging grooves formed in the inner surface of the joint body so as to contain and support the stop ring and to be communicated with each other. Until the connection of the flexible pipe is completed, the stop ring is held engaged with the annular groove and a first engaging groove so as to straddle the grooves. When the flexible pipe is pulled after the completion of the connection, the stop ring moves from the first engaging groove to a second engaging groove to cause the pressing nut to be pulled out of the joint body. This allows the user to confirm that the flexible pipe is normally connected.

Abstract

A gas supply system in which even when the methane value of a mixed gas supplied to an upstream side (main gas supply line (1)) varies, only a gas in the range of predetermined methane values is supplied to a group of predetermined gas apparatuses of each customer to ensure and stabilize operation of the apparatuses. The methane value of the gas flowing through the main gas supply line (1) is measured by a methane value meter (6) at a place near the customer. When the measured methane value is not larger than a threshold, the gas flowing through the main gas supply line (1) is separated into a first gas having a methane value exceeding the threshold and a second gas having a methane value not exceeding the threshold by a gas separator (30). After the separation, the first gas is supplied to a group of first gas consuming apparatuses (such as a gas engine) (10) and the second gas is supplied to a group of second gas consuming apparatuses (such as a burner) (20).

Abstract

Provided are a mixed gas supply apparatus suitable for stabilizing the calorie of a fuel gas such as a city gas, and its composition fluctuation adjusting method. Two packed towers are packed with a common adsorbent. A line extension (S1) of a tower downstream side line (L3a) of a branch line (L3) is made longer than a line extension (S2) of a line (L4a). Midway of the line (L3a), moreover, there are formed a plurality of exits (10), by which the line extension (S1) is made variable. On the basis of the measured value of a calorimeter (7), the openings of flow adjusting valves (V1 and V2) and/or the line extension (S1) of the line (L3a) are suitably adjusted to adjust the calorie fluctuating value of the fuel gas to be supplied to a loading device (5). At first, the calorie is suppressed by the actions of the absorbents in the individual packed towers. By the deviation of the calorie fluctuation phase due to the difference of the branch line extension, moreover, the calorie suppression is further performed, and the calorie fluctuation can be minimized by setting the flow ratio and the line extension (S1) properly.
